[@mursalin3698]

can you explain super(veg) ; in line 3 ? what does it do? "create constructor matching super" - what does it mean?

[@dineshnarwani8473]

"super" is a keyword which is used for calling a constructor, variable or method from parent class. Here, super(veg) is being used for calling constructor from parent class having 1 parameter and giving veg as a argument to a parent class constructor.

[@user-sd5jh5ye4w]

I have a doubt sir, why we created data members private and why we created constructor for veg?

[@rinchenbhutia7376]

What will be the best way to solve the problem?

Methods or variables that accessed using super keyword are from the parent class.

Hlow sir the overall code is interesting but I got stucked in one part only ---WHEN WE CALL ANY FUNCTION ie.(addExtraCheese, addExtraToppings) TWICE IN A ROW IN THE MAIN CLASS THEN IT DOESN'T SHOW ANY INCREAMENT IN EXTRA TOPPINGS OR CHEESE PRICE IT WILL ONLY MAKE INCREAMENT IN TOTAL BILL.
PLEASE ALSO EXPLAIN HOW TO GET RID OF THIS PROBLEM!
